A uniform-density 8 kg disk of radius 0.28 m is mounted on a nearly frictionless axle. Initially it is not spinning. A string is wrapped tightly around the disk, and you pull on the string with a constant force of 39 N through a distance of 0.8 m. Now what is the angular speed?

be subject to a force andchange its motion

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

where is the photo and the answer choices?

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
